On Windows 2000/NT systems, the Environ$ function can be used to retreive certain information from the system, without using any API calls! For example, to retreive the location of the temp directory, use

Debug.Print Environ$("temp")

For the system directory, try

Environ$("windir") & IIf(Len(Environ$("OS")), "\SYSTEM32", "\SYSTEM")

Other environment variables are also available - to see them go to Start | Settings | Control Panel, open the System item, click the Advanced tab, and click the Environment Variables button.

Please note: Environment variables can vary from PC to PC, are user-modifiable, and other than standard items such as WinDir and Temp, Environ should not be entirely relied apon.
